According to the October 2009 issue of Arthritis Care & Research,
there were 480 study participants with knee osteoarthritis who were
compared to 490 healthy controls. Results revealed that prolonged
squatting and cycling were risk factors for knee osteoarthritis.
Knee-bending appeared to be a borderline risk factor for knee
osteoarthritis. Carrying loads, climbing stairs, prolonged standing,
sitting on the floor, and walking up and downhill were not risk factors
for knee osteoarthritis.
Researchers concluded that education is important to teach patients which risk factors may be preventable. When the knee joint is overused, the risk of developing knee osteoarthritis goes up.
